EXHAUST GAS HEAT RECUPERATION DEVICE Russian patent published in 2016 - IPC F01N5/02 F01N13/08 F02G5/02 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in devices for heat recuperation of exhaust gases of internal combustion engines. Device (12) of exhaust gas heat recuperation comprises first pipeline (16), through which exhaust gases of engine (14) are flowing, second pipeline (18), branched from first pipeline (16) and including heat recovery unit (26) allowing heat of exhaust gases act on heat carrier, valve element (34) and drive element (36). Valve element (34) is configured to control exhaust gas flow rate in second pipeline (18). Drive element (36) is located outside of contact with heat carrier flow circulation circuit and is equipped with energy for heating of wax in order to change volume of wax at actuation of valve element (34).

EFFECT: reduced effect of heat on driven element from heat carrier.
